In operation, a pie plate 35 having a layer of dough overlying it, is placed in holder 12, so that extension members 18 engage in the channels in the underside of the plate, thereby centering the pie plate in the holder in proper position to register with matrix34. Matrix 34 carried by plunger 31, is now forced downwards, as by foot operated lever 24, untilthe matrix has effected the dough lining operation (see Fig. 13)', whereupon the pressure is removed, matrix 34 returns to normal, and plate 35v may now be removed and replaced by the next dough covered plate and the operation is repeated.

The bench 11 is designed to accommodate the particular form of pie plate which it is desiredl to use. to be universal so that it will accommodate any yofthe various forms of pie plate shown in- Figs. 2, 5, 8, 11, or 14 interchangeably.

' Figs. 4, 5 and 6 show one form of plate 41 and matrix 40. In this embodiment the plate, Fig. 5, which may be circular in form, is provided with a plurality of sector shapedreceptacles 45, each receptacle having curved side walls and a curved back wall, .which are best shown in the sectional view (Fig. 4). Each receptacle is surrounded by.

ber, shape and arrangement to the number,

shape and arrangement of the receptacles 45 of pie plate 41 (Fig. 5). The projections 49 are slightly smaller than receptacles 45 by an amount equal to the ultimate thickness of a layer of" dough, so that when said4 projections are brought into registry with the dough-lined receptacles, the dough is snugly and evenly lined againstthewall ot the pie plate as is best indicated in dotted lines in Fig. 4. The flanges 50 encircling projections 49', will register with the flanges 46 encircling the receptacle 45. The dough lining operation may be performed manually or mechanically. I'f performed mechanically, matrix 40: will be assembled in a pressfsuch for example as that shown in' Fig. 1 and operated in the manner previously described. If oper-Y ated manually, matrix llO-may be provided with a suitable handle 54 connected to the matrix by a shaft 53, and a frame 42 operable to eiTect co-operative registry of plate 41 and matrix 40(` may be provided'. This frame 42 is provided with suitable registry devices as for example the guide members 44 formedin the side Walls-43 (Fig. 4). These guide members 44 are adapted to receive the notched openings 48 and 52 of the pie plate and matrix respectively. In operation the dough covered plate is placed in the frame 42 so that thenotched openings 48y register with the guides 44. Matrix 4i) is then so placed that the notched openings 52 likewise engage in the guides 44, and matrix 40 is now brought into co-operative registry with plate 41, to cause the lower layer of dough overlying theplate 41, to be snuglyv lined` against the wallsr of the plate' to assume the configuration of said plateas isjindicated in Fig. 4 which shows the relative position of the plate 41 andthe matrix'4() immediately after the dough lining operation hasy beenV completed.

Matrix 40 is n ow withdrawn,fromwplate41,` and the latter is now taken from the frame 42. As

Bench 11 or holder 12 may be designedl lbeads 4'7v (Fig. 5) are replaced by the squared beads 60 and 61. The projections 63 of matrix 55 conform in shape, number and arrangement 90 'to' the shape, number and arrangement of the receptacles 5.7 of plate 56, the projections being smaller by the ultimate thickness of a layer of dough than the receptacles 57. Matrix 55 is provided with a shaft 62 and is designed to be bodily interchangeable with matrix 34 of Fig. 1.

Figs. 10, 11 and 12 show another form of matrix and plate differing fromthe form shown in Figs. 7, 8 and 9 by the omission from the plate 66 of the beads 66 and 61 and the modi-iication of the matrix to correspond. As shown in the drawings the plate 66 is likewise shallower than the plate 56 of Fig. 8. Plate 66 is provided with a plurality'of sector shaped receptacles 67 having bevelled side and back walls 68, the receptacles being surrounded by a plurality of laterally and outwardly projecting smooth anges merging together to denne a smoth topped multiple-unit pie plate surrounded by a peripheral flange occupying the same plane as the partitioning flanges between receptacles. A plate of this type like the plate 76 of Fig. 14 has the advantage over plates provided with outwardly projecting Abeads (such as are shown in Figs. 5 and 8) because smooth topped pie plates are more readily cleaned and oier less resistance to the removal of the baked pies with the result that the risk of damaging the piecrust during the removal operation is greatly reduced when pans of the character shown in Figs. 11 and 14 are employed. It will likewise be observed that pans 66 and 76 are shallower than pans 41 and 56. The pies made in the various plates (Figs. 5, 8, 11l and 14) are all intended to have the cubical contents of the conventional individual' sector shaped pie portion, but where the pieis heaped' above the flanges of the piey plate inI the process of making the same, the Wall area of the pie plate can becorrespondingly reduced. Obviously as the wall area in contact with the dough is reduced, the removal of the baked pie from the pie plate without damage to the dough'is facilitated. Matrix 65 is likewise provided with the shaft '7'1 so as to render said matrix interchangeable with the matrix 34 of the machine` of Fig. 1.

Figs. 18, 14 and `15 illustra-te still another embodiment of pieplate 76 and its associated matrix '75. As appears from a comparison of Figs. l1 and 14 all sharp corners and angles have been removed from the pie plate 76. This is accomplished by rounding'of the corners formed by the merger of the side walls with the angefs land rounding off the angles formed between adjacent side walls and thesidewalls and back walls. Each receptacle 77 is provided with a plurality of vents 8 0`to permit the air underlying 'the lower layer of dough'tjo be forced out of the pie plate when the matrix 75 is brought intoco operative registry with the pie plate 76 as indicated in'thev sectional' view (Fig. 1'3). Byforc- .150

patinageV ing the air out of the plate the formation of air pockets in the lower layer of dough is eliminated. It should, of course, ybe understood that the projections 81 of the matrix conform in shape,

number and arrangement to the receptacles 7'7A of the plate, the projections being smaller than the receptacles by the ultimate thickness of the lower layer of dough. Matrix` is of course, intended to be interchangeable with matrix the machine of Fig. 1. y

It should, of course, be understood that while for purposes of illustration the plates illustrated in Figs. 5, 8, 11 and 14 deiine a circular ligure, the invention is not intended to be so limited as the plates may be made in any preferred shape and for any desired number of sector vshaped or triangular shaped receptacles without departing from the spirit of the invention.

What is claimed is:

In a pie making machine'and in combination,

a frame-work having a holder therein, a plunger, a matrix carried by said plunger, a spring, said plunger being slidably keyed to said holder to move said matrix vertically downwards against the tension of said spring, a pie plate holder, means for yieldably centering a pie plate in said plate holder and relative to the said matrix, an upper anda lower lever, each of said levers being pivotally mounted on said frame work, a pair of rods, one of said rods being pivotally connected to the upper lever and the other pivotally connected to the lower lever, a turn buckle Vadjustably uniting adjacent ends of said rods together, anda pivotal connection between the plunger and the upper lever, said lower lever being operable under fthe application of foot pressure to force said matrix vertically downwards into registry with a plate centered in said plate holder.
